Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.
so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅... -
I am trying to remove the BIOS password for a Dell Latitude 5430 motherboard LA-L591P. So far I think that I have located the BIOS chip but NeoProgrammer says that is detects 3 chips. I have attached the dump from each one. Are any of these the BIOS file? Service Tag: 1DMC1T3. If nyone knows the exact location of the bios chip as well I would greatly appreciate it... -
Hello everyone,
I'm working on a Dell Latitude 5490 with a LA-F401P motherboard that has a very peculiar issue, and I would appreciate your insights.
Initial Problem:
The laptop was completely dead, no signs of life, no power LED.
Action Taken:
I flashed the main BIOS chip with a clean dump. This brought the machine back to life, but with a strange limitation.
Current Situation & The Main Issue:
The laptop now works perfectly when powered through the USB-C port. It charges the battery, powers on, boots into the OS, and functions 100% correctly.... -
Hi
i have dell latitude E7270 with following symptoms:
- takes long time to restart.
- sometimes powers on and then off
- sometimes while working it just dies,
From googling online bios clean could possible resolve this?
i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)
As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.
I reinstall...
